Just dueling because finding a competent Rogue partner is impossible. I have 905 resilience, 22530 health, and I'm hit capped against everything but Mage.
vs. full Deadly Death Knight, I started by putting my DoTs on it, it immediately Lichbornes and grips me. Great. It's immune to fear for 15 seconds and I can't shackle it. I put a renew and ProM up, then disperse. After that, I continued putting my DoTs on the DK. When the 15 seconds of Lichborne was up, I feared it and began casting a Flash Heal in an attempt to fake it out. It instantly uses WoTF on my fear, I cancel my Flash Heal, but the DK doesn't fall for it. I then use Psychic Horror and begin another Flash Heal, it trinkets the Horror, counterspells this Flash Heal, chains it to Strangulate, and I die.
vs. PvE geared Mage, my highest DoT tick is like 500; my Shadow Word: Pain is ticking for 370. My gear is mixed pre-Ulduar best in slots (for hit cap), one piece of Hateful, two pieces of Furious, and the rest is Deadly (include off pieces). I spend the whole match spamming heals, trying to fake out a counterspell, and running around while renewing my DoTs on it. It resists my first Psychic Scream, two Silences, and my Psychic Horror. It WoTFs my second Psychic Scream and trinkets the third. It's nowhere near dead when it kills me.
vs. Deadly Gladiator Rogue, I figure I can survive his first stunlock and save my trinket/dispersion for a more important moment. He drops me to 7600 by the time Kidney Shot wears off, I throw a Shadow Word: Pain on him and fear, which he breaks with WoTF, then he cloaks and vanishes. And then I'm dead.
My only damage was my one SW:P tick. I think he was using his PvE gear, which is all pre-Ulduar best in slots, though.
tl;dr damage is actually much worse than it was pre-patch. Survivability isn't much better than it used to be. No class in battlegrounds or skirmishes has even flinched at dispelling my Vampiric Touch. Mana is still completely terrible, I usually OOM within the first minute of the match. Not much fun.
On the other hand, I am able to kill bad/badly geared Rogues now. That's a plus!
